Description

Technical Field

[0002] Battery equipment is an important energy device in various fields, especially in the transportation, automotive and rail train fields, where battery equipment is increasingly used.

[0003] The production of battery boxes requires that long steel plates be bent three times and then connected end to end to form a U-shaped box. In the process of bending the steel plate with existing bending machines, after three bends, the steel plate just wraps around the bending pressure rod, and the workers need to manually collect the bent box. At this time, one side of the box is still under the pressure rod.

DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] Embodiment 1: A new energy battery box automatic bending device, such as Figure 1-Figure 15As shown, it includes a processing bracket 1, a processing table 101, a control cylinder 102, a moving rod 1021, a connecting sleeve 1022, a fixing ring 1023, a fixing support plate 103, a support frame 104, a rotating rod 205 and a locking mechanism. The processing bracket 1 is fixedly connected to the processing table 101, the fixing support plate 103 is fixedly connected in the processing table 101, the control cylinder 102 is installed in the processing bracket 1, and the moving rod 1021 is slidably connected in the processing table 101. The moving rod 1021 is connected to the telescopic rod of the control cylinder 102, and the control cylinder 102 can control the moving rod 1021 to move on the processing table 10 1, a connecting sleeve 1022 is sleeved on the top of the moving rod 1021, and a support frame 104 is fixedly connected to the top of the connecting sleeve 1022. The moving rod 1021 pulls the support frame 104 to move through the connecting sleeve 1022. A fixing ring 1023 is fixedly connected to the moving rod 1021, and the fixing ring 1023 is located below the connecting sleeve 1022. A rotating rod 205 is rotatably connected to the support frame 104. A locking mechanism is installed on the support frame 104. The locking mechanism locks the rotating rod 205, so that when the support frame 104 and the rotating rod 205 are lowered, they cooperate with the fixed support plate 103 to bend the two ends of the plate.

[0036] During processing, the plate to be bent is sent to the top of the processing table 101, and the fixed support plate 103 provides support for the plate. When the plate is pushed into place, the control cylinder 102 pushes the connecting sleeve 1022 and the support frame 104 to rise by moving the pull rod 1021, and the rotating rod 205 on the support frame 104 rises accordingly and passes through the gap between the plate and the processing table 101. When the support frame 104 is pushed to the highest point, the top surface of the support frame 104 just contacts the plate. At this time, the rotating rod 205 is rotated and made close to the top of the plate, so that the support frame 104 and the rotating rod 205 clamp the plate, and at this time again Start the control cylinder 102, and the control cylinder 102 pulls the moving rod 1021 to descend. At this time, under the action of the locking mechanism, the support frame 104 and the connecting sleeve 1022 cannot descend temporarily. During the process of moving the rod 1021, the locking mechanism can be controlled to clamp the rotating rod 205. When the moving rod 1021 is in contact with the bottom surface of the internal cavity of the connecting sleeve 1022, the moving rod 1021 will pull the support frame 104 down through the connecting sleeve 1022. When the support frame 104 descends, the rotating rod 205 will also descend to pull the plate downward and cooperate with the fixed support plate 103 to bend the plate.

[0037] Embodiment 2: Based on embodiment 1, Figure 3 and Figure 4As shown, the locking mechanism includes a moving frame 2, a connecting spring 201, a moving rod 202, an arc-shaped block 203, a first reset spring 204 and a cylindrical rod 2051. The moving frame 2 is slidably connected to the support frame 104. A connecting spring 201 is provided between the moving frame 2 and the support frame 104. The connecting spring 201 is sleeved on the outside of the connecting sleeve 1022. One end of the connecting spring 201 is fixed to the support frame 104, and the other end is fixed to the moving frame 2. The moving rod 202 is slidably connected to the support frame 104. The end of the moving rod 202 close to the moving frame 2 is wedge-shaped, and the moving rod 20 One end of the wedge matches the moving frame 2. When the moving frame 2 descends, it can push the moving rod 202 to slide at the bottom of the support frame 104. A first return spring 204 is provided between the moving rod 202 and the support frame 104. One end of the first return spring 204 is fixedly connected to the moving rod 202, and the other end is fixedly connected to the support frame 104. An arc-shaped block 203 is fixedly connected to the end of the moving rod 202 away from the moving frame 2. A cylindrical rod 2051 is fixedly connected to the end of the rotating rod 205 away from the rotating shaft. The arc-shaped block 203 can be stuck outside the cylindrical rod 2051 to limit the rotation and reset of the rotating rod 205.

[0038] When the control cylinder 102 pushes the moving rod 1021 to rise, the connecting spring 201 opens the support frame 104 and the moving frame 2, so that the moving frame 2 and the support frame 104 are separated from each other. When the support frame 104 rises to the same height as the top surface of the fixed support plate 103, the support frame 104 is restricted by the fixed support plate 103 and cannot continue to rise. At this time, the moving rod 1021 continues to push the moving frame 2 to rise through the fixed ring 1023, so that the distance between the moving frame 2 and the support frame 104 becomes shorter to compress the connecting spring 201. When the moving frame 2 slides along the support frame 104, under the push of the first return spring 204, the moving rod 202 drives the arc block 203 to slide in the direction close to the moving frame 2, so that the cylindrical rod 2051 on the rotating rod 205 can rotate downward and pass through the hole on the other side of the support frame 104. When the control cylinder 102 pulls the moving rod 1021 to descend, under the action of the connecting spring 201, the support frame 104 will not descend. The moving rod 1021 first slides downward along the connecting sleeve 1022, and the moving frame 2 slides downward along the support frame 104. During the sliding downward process of the moving frame 2, the moving frame 2 will push the moving rod 202 and the arc-shaped block 203 to approach the cylindrical rod 2051, so that the arc-shaped block 203 is clamped outside the cylindrical rod 2051 to limit the rotation rod 205 from rotating upward and resetting. When the moving rod 1021 is in contact with the bottom surface of the internal cavity of the connecting sleeve 1022, the moving rod 1021 will pull the support frame 104 down through the connecting sleeve 1022, and the support frame 104 and the rotating rod 205 will jointly pull the plate down, and at the same time cooperate with the fixed support plate 103 to bend the two ends of the plate upward.

[0039] like Figure 3The figure also includes a bracket 105 , which is fixedly connected to the processing table 101 . The bracket 105 is used to support the moving frame 2 and limit the height of the moving frame 2 .

[0040] During the descent of the support frame 104 and the mobile frame 2, the mobile frame 2 will first contact with the bracket 105. At this time, the mobile frame 2 no longer descends, and the control cylinder 102 continues to pull the moving rod 1021 to descend. The moving rod 1021 descends and pulls the support frame 104 to continue to descend through the connecting sleeve 1022. The connecting spring 201 is compressed, and the distance between the support frame 104 and the mobile frame 2 becomes shorter. At this time, under the push of the first return spring 204, the moving rod 202 and the arc block 203 slide in the direction close to the mobile frame 2 to make the arc block 203 disengage from the cylindrical rod 2051. At this time, the rotating rod 205 and the cylindrical rod 2051 are no longer restricted by the arc block 203, so that the bent plate is no longer clamped by the support frame 104 and the rotating rod 205.

[0041] Embodiment 3: Based on embodiment 2, Figure 5-Figure 7 and Fig.11 As shown, it also includes a fixed guide frame 206, a lifting rack 207, a support spring 2071, a transmission gear 208, a fixed guide rail 3 and a fixed pressure rod 3001. The fixed guide frame 206 is fixedly connected to the support frame 104, and the lifting rack 207 is slidably connected in the fixed guide frame 206. The lifting rack 207 and the fixed guide frame 206 are connected through the support spring 2071. One end of the support spring 2071 is fixedly connected to the fixed guide frame 206, and the other end is fixedly connected to the lifting rack 207. The transmission gear 208 is fixedly connected to the rotating shaft of the rotating rod 205, and the transmission gear 208 is meshed with the lifting rack 207. The fixed guide rail 3 is fixedly connected to the processing table 101, and the fixed pressure rod 3001 is fixedly connected to the fixed guide rail 3. The fixed pressure rod 3001 is located directly above the lifting rack 207.

[0042] During the process of the support frame 104 being pushed up, after the cylindrical rod 2051 on the rotating rod 205 passes through the gap between the plate and the processing table 101, when the lifting rack 207 contacts the fixed pressure rod 3001, as the rotating rod 205, the fixed guide frame 206 and other components continue to rise, the lifting rack 207 is restricted and cannot rise. During this process, the support spring 2071 between the lifting rack 207 and the fixed guide frame 206 is compressed. When the lifting rack 207 is restricted by the fixed pressure rod 3001, the support frame 104 continues to rise and drives the rotating rod 205 and the transmission gear 208 to rise. The transmission gear 208 is driven to rotate by the lifting rack 207, and then drives the rotating rod 205 to swing downward, so that the cylindrical rod 2051 on the rotating rod 205 passes through the support The hole at the other end of the frame 104 is formed in the process that the movable pull rod 1021 drives the support frame 104 to descend, and the arc block 203 is clamped on the outside of the cylindrical rod 2051 to limit the rotating rod 205. When the movable frame 2 contacts the bracket 105 and stops descending, as the support frame 104 continues to descend, the arc block 203 is no longer clamped on the outside of the cylindrical rod 2051. At this time, the rotating rod 205 and the cylindrical rod 2051 are released from the restrictions, and the lifting rack 207 is no longer restricted. Under the push of the support spring 2071, the lifting rack 207 will slide upward along the fixed guide frame 206, and the lifting rack 207 rises and drives the rotating rod 205 to swing upward through the transmission gear 208, so that the rotating rod 205 automatically disengages from the bent plate, and the restriction on the plate is automatically released.

[0043] like Figure 2 , Figure 3 and Figure 8 As shown, it also includes a support plate 106, a sliding bending block 301, a bending rack 302, a second return spring 3021, a bending gear 303, a belt drive group 304, a rotating frame 305 and a supporting mechanism. The top of the processing bracket 1 is fixedly connected to the support plate 106, and the support frame is located in the processing table 101. The sliding bending block 301 is slidably connected in the fixed guide rail 3. When the sliding bending block 301 slides along the fixed guide rail 3, the plate is bent twice. The processing bracket 1 is slidably connected to the bending rack 302, and the bending rack 302 is connected to the processing bracket 1. The two rotating frames 305 and 306 are connected by a second return spring 3021, one end of the second return spring 3021 is fixed on the bending rack 302, and the other end is fixed on the processing bracket 1. A bending gear 303 is rotatably connected in the processing table 101, and a rotating frame 305 is rotatably connected on the processing table 101. The bending gear 303 and the rotating frame 305 are connected by a belt transmission group 304. The bending gear 303 drives the rotating frame 305 to rotate through the belt transmission group 304. The supporting mechanism is installed in the processing table 101, and the supporting mechanism provides support to the plate from the inside.

[0044] When the movable rod 1021 pulls the support frame 104 downward, the movable frame 2 first descends and drives the support mechanism to operate, and the support mechanism will provide support for the plate from the inside. When the rotation rod 205 is released from the restriction, the rotation rod 205 will rotate upward and break away from the bent plate. At this time, the plate bent upward at both ends contacts the support plate 106. At this time, the support plate 106 provides support for the plate after the initial bending, and the support frame 104 is continued to be pulled by the movable rod 1021 and moves downward. During the process, the support frame 104 contacts the bending rack 302 and pushes it to slide downward. The bending rack 302 descends to compress the second return spring 3021. When the bending rack 302 descends, it drives the rotating frame 305 to rotate through the bending gear 303 and the belt transmission group 304. When the rotating frame 305 rotates, it drives the sliding bending block 301 to slide along the fixed guide rail 3. When the sheet after the initial bending contacts the supporting plate 106, the sliding bending block 301 just touches the outer wall of the sheet after the initial bending. When the support frame 104 is in contact with the movable frame 2, the sliding bending block 301 just completes the secondary bending of the sheet, and the sliding bending block 301 is out of contact with the sheet at this time. The sheet is now bent into a U-shaped box body, and the bent sheet can then be taken out. When the movable pull rod 1021 pushes the support frame 104 to rise and reset, the second reset spring 3021 pushes the bending rack 302 to rise and reset, and the bending rack 302 drives the rotating frame 305 to rotate and reset through the bending gear 303 and the belt transmission group 304, and the sliding bending block 301 slides and resets along the fixed guide rail 3.

[0045] like Figure 3 and Fig. 9 As shown, the supporting mechanism includes a lifting rod 4, a fixed straight rod 401, a return spring 402, a rotating support plate 403 and an arc-shaped slide 404. The lifting rod 4 is slidably connected in the processing table 101, and the fixed straight rod 401 is fixedly connected to the lifting rod 4. A return spring 402 is arranged between the fixed straight rod 401 and the processing table 101. One end of the return spring 402 is fixed to the fixed straight rod 401, and the other end is fixed to the processing table 101. An arc-shaped slide 404 is provided on the top of the lifting rod 4. A rotating support plate 403 is rotatably connected in the processing table 101. The rotating support plate 403 is rotatably connected to the lifting rod 4, and the rotating support plate 403 cooperates with the arc-shaped slide 404. When the lifting rod 4 descends, the rotating support plate 403 rotates in the processing table 101 driven by the arc-shaped slide 404.

[0046] When the movable frame 2 is lowered, it contacts with the fixed straight rod 401. As the movable frame 2 continues to lower, the fixed straight rod 401 and the lifting rod 4 lower synchronously, the return spring 402 is compressed, and when the lifting rod 4 lowers, the arc slide 404 at its top lowers and makes the rotating support plate 403 rotate around the lifting rod 4 in the direction close to the plate. When the movable frame 2 contacts with the bracket 105, the fixed straight rod 401 and the lifting rod 4 no longer lower, and the rotating support plate 403 just contacts with the inner wall of the plate. At this time, the longer side of the plate bent upward is located between the fixed support plate 103 and the rotating support plate 403. When the sliding bending block 301 slides along the fixed guide rail 3 and contacts the plate, the rotating support plate 403 provides support from the inside of the plate to perform secondary bending on the plate. When the movable frame 2 rises, under the push of the return spring 402, the fixed straight rod 401 and the lifting rod 4 rise and reset, and the rotating support plate 403 rotates and resets under the drive of the arc slide 404.

[0047] like Figure 2 and Fig.10 As shown, it also includes a sliding door 5, an L-shaped sliding rod 501, a propping spring 502, a U-shaped fixed plate 503, a transmission cam 504, a rotating cam 506 and a rotating pull rod 507. The sliding door 5 is slidably connected in the processing table 101, and the L-shaped sliding rod 501 is slidably connected on the processing bracket 1. The L-shaped sliding rod 501 passes through the fixed support plate 103 and is slidably connected thereto. A propping spring 502 is provided between the L-shaped sliding rod 501 and the processing table 101, and one end of the propping spring 502 is fixed to the L-shaped sliding rod 501. The other end is fixed on the processing bracket 1, and a U-shaped fixed plate 503 is fixed on the fixed support plate 103. A transmission cam 504 is rotatably connected to the U-shaped fixed plate 503. The transmission cam 504 is rotatably connected to a transmission pull rod 505 at an eccentric position. The other end of the transmission pull rod 505 is rotatably connected to the L-shaped sliding rod 501. The transmission cam 504 is coaxially fixed with a rotating cam 506. The rotating cam 506 is rotatably connected to a rotating pull rod 507 at an eccentric position. The other end of the rotating pull rod 507 is rotatably connected to the sliding warehouse door 5.

[0048] During the descent of the mobile frame 2, the L-shaped sliding rod 501 will be pushed down and the supporting spring 502 will be compressed. The L-shaped sliding rod 501 descends and drives the transmission cam 504 to rotate through the transmission rod 505, and the rotating cam 506 rotates synchronously therewith. When the rotating cam 506 rotates, the sliding door 5 is pulled along the fixed support plate 103 to slide through the rotating rod 507. When the mobile frame 2 descends to the lowest point, the L-shaped sliding rod 501 pulls the transmission cam 504 to rotate 180 degrees through the transmission rod 505, and the sliding door 5 is fully opened. At this time, the bent box can be taken out from the side of the processing table 101.

[0049] like Figure 11-13As shown, it also includes a sliding top plate 6, a wedge-shaped push block 601, a sliding positioning plate 602, a positioning spring 603, a feeding rack 7, an electric guide rail 701, a sliding push rack 702, a moving push rod 703, a moving push rod 704 and a third reset spring 7041.

[0050] When the workpiece is pushed, the electric slider of the electric guide rail 701 will drive the sliding pusher 702 to slide in the direction close to the processing table 101. During this process, the sliding pusher 702 pushes the workpiece on the feeding rack 7 into the processing table 101. When the right end of the workpiece and the right end of the moving push rod 704 are located in the same vertical plane, the sliding pusher 702 will push the moving push rod 704 to slide in the direction close to the sliding top plate 6 through the moving push rod 703. When the moving push rod 704 contacts the sliding top plate 6, the right end of the workpiece also contacts the sliding top plate 6. At this time, the moving push rod 704 will push the sliding top plate 6 to slide right along the fixed guide rail 3, and the sliding top plate 6 will pull the wedge push block 601 to move right. At this time, the wedge push block 601 will push the sliding positioning plate 602 to move in the direction close to the workpiece and compress the third return spring 7041. The two sliding positioning plates 602 move toward the workpiece from both sides at the same time, and adjust the workpiece to the center position in the processing table 101 to avoid the workpiece tilting and affecting the bending effect.

[0051] like Figure 13-Figure 15As shown, it also includes a sliding push frame 705, a guide rod 706, a moving block 707, a push spring 708, a moving push frame 709 and a moving discharging frame 710. The sliding push frame 705 is slidably connected to the feeding frame 7, the guide rod 706 is fixedly connected to the feeding frame 7, the moving block 707 is slidably connected to the guide rod 706, the sliding push frame 705 is slidably sleeved outside the guide rod 706, a push spring 708 is provided between the moving block 707 and the feeding frame 7, the push spring 708 is sleeved outside the guide rod 706, and the push spring 708 is sleeved outside the guide rod 706. One end of the spring 708 is fixed to the moving block 707, and the other end is fixed to the feeding rack 7. The processing table 101 is slidably connected to the outside with a moving discharging rack 710. The moving discharging rack 710 slides along the fixed support plate 103 and pushes the bent battery box outward. A moving pushing frame 709 is fixedly connected to the moving discharging rack 710. The bottom of the moving block 707 passes through the moving pushing frame 709 and is slidably connected thereto. When the moving block 707 slides along the guide rod 706, the moving discharging rack 710 is driven to slide through the moving pushing frame 709.

[0052] When pushing the plate, the sliding pusher frame 702 will drive the moving block 707 to slide along the guide rod 706 toward the direction close to the processing table 101 through the sliding pusher frame 705. At this time, the pushing spring 708 is compressed, and the moving block 707 drives the moving discharging frame 710 to slide out of the processing table 101 through the moving pushing frame 709. After the plate is bent into a U-shaped box, the electric slider on the electric guide rail 701 drives the sliding pusher frame 702 to slide away from the processing table 101. At this time, under the push of the pushing spring 708, the moving block 707 pushes the sliding pusher frame 705 to slide and reset along the guide rod 706 away from the processing table 101. At this time, the moving block 707 will drive the moving discharging frame 710 to slide into the processing table 101 through the moving pushing frame 709, and the moving discharging frame 710 pushes the box formed in the processing table 101 outward.
